Title: Guide structure for carrier of picture reader
Inventor: ISHIDA SATOSHI
IPC: H04N1/107
Filed: 1988-11-18
Abstract: PURPOSE:To accurately maintain the interval between the surface of an original and a carrier through simple constitution by forming a guide shoe slenderly in the extending direction of a rail, and providing both the ends of the shoe with engaging hooks, and bending their tip ends inside so as to hold the carrier 3 while keeping a clearance. CONSTITUTION:The guide shoe 12 is formed into a slender shape in the extending direction of the rail 2, and the engaging hooks 13 are provided at both the ends of the shoe. The engaging hook 13 is manufactured by bending both the ends of the shoe 12 upward, and further, bending the tip ends inside so that the engaging hook 13 and both the end parts of the carrier 3 are engaged while keeping the clearance 15. A contact consisting of a receiving groove 17 and a protruding strip 14 in the direction intersecting the rail orthogonally is provided between the center of the back surface of the guide shoe 12 and the opposing part of the carrier 3. The dislocation of the shoe 12 in the sliding direction of the carrier is obstructed by the engagement of the protruding strip 14 and the receiving groove 17, and downward disengagement is obstructed by the engagement of the engaging hook 13 and the end part of the carrier 3. Since it can rock while centering the contact part of the protruding strip 14 and the groove 17, uneven contact can be prevented even though the shoe 12 is made sufficiently long.

The polarity of the waveform of the voltage impressed on the picture element by the driving means 2 and 3 for the gradation expressing period according to the gradation which should be expressed is inverted between a term when the polarity of the modulation alternating inversion signal MX is switched and a term when it is not switched. Therefore, the DC voltage is not impressed on the picture element over two succeeding terms. Thus, the gradation display in the data thinning out system is performed without impressing the DC voltage on the picture element.

Filed: 1990-10-31
Abstract: PURPOSE:To form crystals and films of broad materials by disposing mercury in a molten state in a gaseous oxygen atmosphere contg. ozone in a plane state and dropping a liquid material onto the surface of the mercury. CONSTITUTION:The inside of a housing 1 is evacuated to a prescribed vacuum degree by a vacuum pump 3 and thereafter the gaseous oxygen is supplied into the housing 1. The supplied gaseous oxygen is irradiated with UV rays from a UV ray source 32 through a quartz glass window 31. After ozone is generated in the supplied gaseous oxygen, the mercury 11 is introduced into the housing 1 and the mercury 11 is disposed in the plane state in a developing chamber 6. The liquid material to be subjected to the crystal or film formation is dropped onto the surface of the mercury 11 to develop the liquid material on the mercury surface to form the crystal or film. The ozone having the higher activity than the oxygen is incorporated into the oxygen introduced into the housing in this method and, therefore, the mercury surface is further activated if the ozone is adsorbed to the mercury surface. Since the mercury surface is imparted with the higher hodrophilicity, the aq. soln. is more uniformly developed than this soln. is developed in the gaseous oxygen.
